TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patentll'o. 380,792, dated Aprill0, 18881.

Application tiled June 1, 1886. Serial No. 203,880. (No model.) Patentedin England May 24, 1886, No. 6,935; in France August 5, 1886, No.177,787; in Germany August 13, 1886, No. 39,044, and in Austria-HungaryNovember 7, 1886, No. 47,566

and No.11,812.

To a@ whom, it may concern.-

Be it known that I, ADOLPHE PRosrER EG- GIs, of Fribourg, inSwitzerland, have invented a new and useful Improvement in Type-W'ritingMachines, of which the following is a specilication.

Letters Patent for this invention have been duly granted to me, asfollows: In Great Britain, No. 6,935, dated May 24, 1886; inAustria-Hungary, No. 47,566 and No. 11,812, dated November 7, 1886; inFrance, No. 177,787, dated August 5, 1886, and in Germany, No. 39,044,dated August 13, 1886.

My new type-writer combines both the capital letters, the small letters,the ligures, signs, and the punctuations, 82o., and is capable oiprinting all of these, and it is of great simplicity and moderate cost.

In the accompanying drawings, Figure 1 is a plan view of my type-writer.Fig. 2 is a front elevation of the same. Fig. 3 is a sectional elevationat the line my. In this gure the mechanism is shown at the moment inwhich it is printing one letter. Fig. 4 is a side elevation with asection through y z. Fig. 5 shows au inverted plan of the movableprinter taken out of the apparatus.

In all the figures similar letters refer to simi-l f lar pieces.

On a plate, A, areafiXed-two guides, B B,

between which the beveled sliding footplate D is moved. The paper, F, isplaced around the cylinder E,which is secured upon the footplate D, asit is shown by Fig. 4, and the paper is held in place by means of afixed rod, G,

and a movable rod, G. The cylinder E is turned by means of a button, Aratchet or toothed wheel, e, and pawl e regulate the amount which thebutton E can be turned and determine herebylthe space between two lines.

A toothed rack, H, affixed to the foot-plate D, is intended to cause thepaper to advance one or more teeth at a time for each letter printed.One guide-plate B bears a support, K, with a lever, k, pivoted thereto,and a pawl, 7c', engaging the tooth-rack H. On another support or post,L, affixed upon the plate A, bears a lever, Z, whose oftic'e is to putthe pawl cout of gear by pressing the outer end ofZ downward with thenger, when the footplate D is to be moved backward in its slideway.

Upon the corners ofthe plate A are afxed three pillars, ac as, whichbear a plate, A. There is a large circular opening in the plate A,closed by means of the disk I when the apparatus is at rest. Said diskor circularshaped plate I is aiixed luy-means of a central bolt, z', toa frame, J, hinged to the back edge of the plate A by means of hinges j.Plate I can be revolved around the bolt z'. A spring, j', also affixedunderneath the plate A', presses the frame J, as well as plate I,upward, so as to maintain the same in the plane of the plate A', asshown by Fig. 2. The plate or disk I bears on its upper face twobracketed arms, C and S, of a peculiar shape and provided with knobs Cand S. The lower face of I is provided with a circular range of types,one half of which is composed of capital letters and figures, the otherhalf of small letters and punctuation-marks, as shown in Fig. 5.

Two springs, M M, alixed to the frame J, are provided withink'ing-rollers m m, which are pressed against the types of plate I toink the'same.

There is a stud, N, (see Fig. 2,) secured upon the under side of theframe J, and the oflice of said stud is to press down the lever la asthe disk I and frame J are depressed in the act of printing, saidmovement causing the' track H and foot-plate D to advance one tooth,thus feeding along the cylinder E and paper, F. The plate A is,moreover, provided with a circular range of openings, O, disposed andformed so as to give passage to the pointed end of one of the arms G orS when the latter is pressed downward. Each of those openings is markedwith aletter or a figure. The position of the arm C upon the plate I isdetermined in such a manner so that the companion letter or ligure ofany selected capital letter or figure on the plate A, and which standsfor the opening in which said pointed end is pressed down, shallsimultaneously with such selection come in place and with the depressionof the plate I be printed upon the paper, F. The position of hook S uponthe plate I is determined nlike manner, so that the small letters andpunctuations can in like manner be printed upon the paper, F.

The annularshaped opening Q, in the plate A permits of the passage ofthe pointed end ofthe arm Swhen the pointed end of the arm C' is pressedinto one of the openings O in the4 act of printing, or the pointed endof arm G when S is pressed into one of said openings. An opening, It,placed at the periphery of the plate I, provides for supplying theinkingrollers m m with color when they become dry.

rIhe working of my type-writer is as follows: If you Wish to print, forinstance, the capital letter A or the figure 5, you take in your handthe knob C and tur-n the plate I until the pointed end of arm C isplaced over the opening of letter A or figure 5, and you press the knobdown, and at the same time depress the plate I and impress the type A orligure 5 upon the paper. If you have to complete a word--forinstance,ApriW-you take hold ofthe knob S and turn the plate I in thedirection of the arrow until the arm Ss placed over the opening marked Iand press the knob downward. ThestudN operates upon lever k and pawl k',depressing them and moving the rack H, plate D, and cylinder E, andcausing the paper, F, to advance the necessary amount, andjust as thefeed is completed and the paper stopped, the type pis pressed downwardand impressed upon the paper the right distance from A, and thesemovements are repeated for each letter printed. Thelever k is returnedto its normal position by a suitable spring, or by a counter-weight, asshown by dotted lines in Fig. 2. lVhen the end of each line of printingis finished, the button Eis turned, revolving the cylinder and advancingthe paper, F, a distance equal to one or more teeth of the rack e. Thelever Z is pressed downward at its outer end, thereby raising its innerend, which lifts the pawl la out of the teeth of the rack H, and freesthe rack, so that the sliding foot-plate D, the cylinder E, and paper,F, can be pushed backward to the starting-point, so as to beginanotherline.

I claim as my invention--` l. The plate A', having a central openingtherein, letters, figures, and marks arranged in an arc around one sideof said opening, and perforations in said plate opposite each of them,in combination with a pivoted frame, J, hinged to said plate upon oneedge, a disk, I, pivotally supported upon said frame and having typeupon its under surface in opposite sets near the periphery,inking-rollers upon arms secured to the frame J, arms and knobs C S,pointers C S', and a cylinder for the paper, and mechanism,substantially as specified, for operating the same, substantially as setforth.

2. The plates A and A' and con necti ng-posts, forming the frame of themachine, the plate A having a circular opening therein, in combinatonwith the revolving type-disk I, the pivoted frame J, carrying saidtype-disk, the stud N upon the frame J, the post or support K upon theplate A, the lever k and pawl k', connected to said support K, the rackH, sliding foot-plate D, and the post L and lever Z, for releasing therack and raising the pawl, substantially as specified.
